WILLIAM CARTER, OF COLUMBUS, INDIANA.

Specification forming part of Letters Patent No. 93,596, dated August10, 1869.

d' To all whom it may concern: y

Be it known that I, WILLIAM CARTER, of Columbus, in the county ofBartholomew and State of Indiana, have invented new and usefulImprovements in Device for Applying Steam to Wool in Process of Cardingand Spinning, and to Cloth in Process of Finishing; and I do herebydeclare that the following is such a full, clear, and exact descriptionthereof as will enable skilled artisans to make and use the same,reference being had to the accompanying drawing, and to the letters ofreference marked thereon, making part of this specification.

This invention relates to improvements in device for applying steam towarm and soften wool in process of carding and spinning, and to cloth inprocess of iiuishing, and other similar purposes, and has for its objectto more completely modify and control the force with which the steamissues upon the wool or cloth, to render it of the proper hygrometriccondition, and to provide for more eil'ectually drawing oi' the water ofcondensation from the device; audit consists in surrounding asteaminduction pipeleading from a boiler, or other steam-generatingvessel, with a series of two or more concentric tubes or jackets,arranged in suitable relation to the carding-machines, spinning-jacks,or cloth finishing machines, the steam-pipe and surrounding jacketsbeing perforated to admit of the escape of the steam upon the slubs,roping, or cloth as they pass into or through the machine, and, inconnection therewith, the arrangement of eduction-pipes furnished withstop-cocks, and connecting the induction pipe, and the several chambersformed by the surrounding jackets, each separately with the waste-pipe,by means of which not only the water of condensation may be drawn fromeach separately, butthe pressure or force of the steam in each may alsobe regulated as may be required, thereby obviating the chief difcnltiesheretofore experienced in the application of steam to thesepurposesviz., to prevent the water oi' condensation from being ejectedupon the Wool and cloth, and to subdue the force of the steam, andreduce it to the proper hygrometric condition to produce the desiredeffect upon the wool and cloth.

Figure l is a vertical longitudinal section of my improved device forthe above speciiied purpose, showingV the parts and the manner in whichthey are arranged, taken on the line 4r, Fig. 2. Fig. 2 is a transversesection of Fig. l, taken on the line y y.

The same letters of reference indicate like parts in the severalfigures.

Ais a steaminduction pipe, connecting with any suitable steam-boiler orother steam-generating vessel. Portions of this pipe, suitably situatediu connection with the machines to which it is to be applied, arepierced with small holes along its top for the escape of the steam intothe surrounding chamber B,formed by the concentric tube C. i

The tube C is pierced with small holes along its side for the escape ofthe steam into the surrounding chamber D, formed by the externalconcentric tube E, from which it issues through a longitudinal slit orsmall holes in the top of tube E upon the slubs, roping, or cloth asthey are fed into, or passing through, the machine. The device, as hereshown, is composed ot the induction-pipe A, concentric tubes or jacketsC and E, and eduction-pipes- F G H. rIhe tubes C and E are screwed toanges on the heads J, and the induction-tube A passes through bothheads, as shown.

In order to draw ofi' the water of condensation from, and regulate thepressure and hygrometric condition of the steam in each ofthe chambersand the induction-tube, they are connected separately by theeduction-tubesF, G, and H, each being furnished with a stopcock, withthe Waste-pipe I, the construction, arrangement, and operation of Wh ichwill now be described.

A great `portion of the water of condensation is produced in theinduction-pipe A, which,

in other inventions for a similar purpose, is

allowed to escape into the surrounding chamber through the perforationsin the pipe, these perforations being situated in the bottom of thepipe, and thus water is frequently carried up by the force of the steam,and ejected upon the Wool and goods to their great injury; hence thenecessity for arranging the perforations for the escape of the steamalong the top of this pipe, and providing an eduction-pipe, F, to conveythe water directly from the induction-pipe, in order to prevent itsescaping into the surrounding chamber.

G is also an eduction-pipe, provided with a stop-cock andconnecting-chamber, B, as shown, with lthe waste-pipe I, and has noconnection with either pipe A or chamber D. This pipe subserves thepurpose of conveying olf the Water that may be condensed inchamber B,and by means of the stop-cock in this pipe both the pressure andhygrometric eondition of the steam in chamber D may be reg ulated. Whenthe steam is too moist and the pressure too great, the cock should .beopened a little, and when the steam is too dry and the pressure too`Weak, it may' be regulated by closing the cock partially.

H is an eduction-pipe furnished with a stopcock, and connects chamber Dwith wastepipe I, and has no connection with either chamber B or pipe A,and is mainly employed to convey oi the Water of condensation fromchamber D, the hygrornetric condition and pressure of the steam in whichmay also be regulated, to some extent, by the stop-cock, in a similarmanner as by the stop-cock in pipe G.

The admission of" steam into the device is regulated by a stop-cock, K,in theinduetonupe.

l Having thus fully described my invention, what I claim as new, anddesire t0 secure by Letters Patent, is-.

The combination and arrangement of induction-pipe A, the surroundingperforated pipes or jackets C and E, forming the chambers B and D, andhead J with flanges to which the jackets are screwed, and theeduotion-pipes F, G, and H, furnished with stop-cocks, and connectingthe inductionpipe A and chambers B and D with the Waste-pipe I, allcombined and arranged to operate in the manner sub-v stantially as setforth.

WILLIAM CARTER.
